There has been a continuing interest in the sterols and sterodis of marine organisms. The most exciting results of recent studies have been the characterization of a host of novel sterols, many with unique alkylation patterns in the side chain, but some with modified ring structures. The isolation and characterization of three sterols from the Korean alga codium fragile are presented. The major sterol was (24S)-24-ethylcholesta-5,25-dien-3β-ol (clerosterol) and two minors are codisterodl and cholesterol.
